The consensus on the diagnosis and treatment of elderly myelodysplastic neoplasm in China (2024) MDS Professional Committee of Hematology Branch of Chinese Geriatrics Society Journal of Diagnostics Concepts & Practice    2024, 23 (03): 285-296.   DOI: 10.16150/j.1671-2870.2024.03.006 Abstract （1612）   HTML （79）    PDF（pc） （1106KB）（3731）       Knowledge map    Save Myelodysplastic syndromes (MDS) are a heterogeneous group of myeloid tumours originating from haematopoietic stem/progenitor cells, with a high prevalence in the elderly. Epidemiological surveys in Europe and the United States have revealed that the incidence of MDS is (4-5)/100 000, which increases with age，and the median age at diagnosis of MDS patients reaches 73-76 years. In Shanghai, China, according to the World Health Organization (WHO) 2008 diagnostic criteria, the average incidence rate was 1.51/100 000, and the median age of onset of MDS was found to be 62 years old in a survey conducted in 3.9 million people from 2004 to 2007, of which about one-third of the patients would be transformed into acute myeloid leukemia (AML), and 53% of the patients would die due to infections, haemorrhages, or comorbidities triggered by cytopenias. Elderly MDS patients have their own characteristics in terms of both treatment choices and disease prognosis due to more comorbidities and weaker health. Clinical characteristics of elderly MDS patients include slightly higher white blood cell count, haemoglobin level and more bone marrow blasts than those of young patients, while neutrophil count and platelet count are significantly higher than those of young patients; the number of mutations in elderly MDS patients is higher, with an average of 1.8 mutations per patient, among which the mutations in ASXL1, TET2, SF3B1, STAG2, SRSF2 and TP53 are more common; while the number of mutations in younger patients averages 1.2 per person, among which U2AF1, ASXL1 and RUNX1 mutations are more common. Allogeneic haematopoietic stem cell transplantation (allo-HSCT) is the only curative treatment for MDS, and myeloablative transplantation is feasible in young patients, but only reduced-intensity conditioning (RIC) allo-HSCT can be performed in elderly patients.The natural course and prognosis of elderly MDS patients varies considerably, and the MDS Composite Prognostic Score, which is composed of the composite age (>70 years old), vulnerability index, and IPSS prognostic subgroups, is able to better predict the tolerance of chemotherapy and adverse treatment effects in MDS patients. This consensus is based on the latest evidence-based data in the study of MDS in the elderly at home and abroad, and has been discussed by the experts of the group, which aims to standardise the diagnosis and the whole management of treatment for elderly MDS patients in China.

Summary and interpretation of the World Health Organization “Global Report on Hypertension” ZHANG Dongyan, LI Yan Journal of Diagnostics Concepts & Practice    2024, 23 (03): 297-304.   DOI: 10.16150/j.1671-2870.2024.03.007 Abstract （1969）   HTML （54）    PDF（pc） （945KB）（3340）       Knowledge map    Save In 2023, the World Health Organization (WHO) released the first document of “Global report on hypertension—The race against a silent killer”. which covers the global prevalence and management of hypertension, analyzes the mortality and disease burden caused by hypertension, explores the risk factors for hypertension, evaluates the cost-effectiveness of blood pressure treatment, and presents successful examples of hypertension management in many countries, especially the global implementation of the WHO-launched HEARTS project for hypertension control. Hypertension is a significant global public health challenge with severe health implications. Over the past 30 years, the number of people with hypertension (defined as systolic blood pressure ≥140 mmHg or diastolic blood pressure ≥90 mmHg, or taking antihypertensive medication) has doubled, rising from 650 million in 1990 to 1.3 billion in 2019. Among the global hypertensive population aged 30-79, approximately 54% have been diagnosed, of which 42% are receiving antihypertensive treatment, and only 21% have controlled blood pressure. In 2019, elevated systolic pressure was responsible for over half of cardiovascular disease deaths globally. Increasing the global hypertension control rate to 50% could prevent 76 million deaths from 2023 to 2050. Population-level risk factors for hypertension include high salt and low potassium intake, alcohol consumption, physical inactivity, and air pollution. WHO advocates for the prevention and control of hypertension through measures such as reducing dietary sodium intake, increasing potassium intake, limiting alcohol consumption, quitting smoking, increasing physical activity, and improving air quality. In terms of treatment, WHO guidelines recommend antihypertensive medication for individuals with systolic blood pressure ≥140 mmHg or diastolic blood pressure ≥90 mmHg. For specific populations, it is also recommended to start antihypertensive treatment when systolic blood pressure is between 130-139 mmHg. The use of single-pill combination therapy is also advised to improve adherence and persistence in treatment. The prevalence and management of hypertension in China are also noteworthy. Hypertension is a major cause of mortality and disease burden in the Chinese population. By learning from global successes in hypertension management, China can enhance its efforts in the prevention, control, and monitoring of hypertension, particularly by promoting the application of the HEARTS technical package to improve hypertension management. This report aims to draw attention to major non-communicable diseases, particularly hypertension, as a public health challenge. Through detailed data analysis and successful case studies, the report underscores the importance of hypertension prevention and control, providing scientific evidence for policy-making across countries. This collective effort aims to achieve the global goal of a 25% relative reduction in uncontrolled hypertension prevalence by 2025 compared to 2010. This article will interpret briefly the reports based on the prevalence and management of hypertension in China. Table and Figures | Reference | Related Articles | Metrics | Comments（0）

Superconducting nanostrip single photon detectors fabricated of aluminum thin-films Yuting Jiang, Xingyu Zhang, Hui Zhou, Xiaofu Zhang, Hao Li, Lixing You Superconductivity    2024, 10 (0): 100096-.   DOI: 10.1016/j.supcon.2024.100096 Abstract （166）   HTML （162）    PDF（pc） （1122KB）（2332）       Knowledge map    Save We systematically investigated the detection performance of Al nanostrips for single photons at various wavelengths. The Al films were deposited using magnetron sputtering, and the sophisticated nanostructures and morphology of the deposited films were revealed through high-resolution transmission electron microscopy. The fabricated Al meander nanostrips, with a thickness of 4.2 nm and a width of 178 nm, exhibited a superconducting transition temperature of 2.4 K and a critical current of approximately 5 μA at 0.85 K. While the Al nanostrips demonstrated a saturated internal quantum efficiency for 405-nm photons, the internal detection efficiency exhibited an exponential dependence on bias current without any saturation tendency for 1550-nm photons. This behavior can be attributed to the relatively large diffusion coefficient and coherence length of the Al films. By further narrowing the nanostrip width, the Al-SNSPDs remain capable of effectively detecting single telecom photons to facilitate practical applications.

Numerical modelling of electromechanical coupling behaviors in HTS coil with implementation of H formulation in FE software Huadong Yong, Dong Wei, Yunkai Tang, Donghui Liu Superconductivity    2024, 10 (0): 100097-.   DOI: 10.1016/j.supcon.2024.100097 Abstract （399）   HTML （378）    PDF（pc） （3029KB）（2266）       Knowledge map    Save (Re)Ba2Cu3O7-x (REBCO) coated conductors (CCs) have attracted considerable concern because of their outstanding current carrying capacity in magnetic fields of high strengths. A huge electromagnetic force is generated in the superconducting coil when conducting large currents in strong magnetic field. Thus, management of stress and strain has become a key technical challenge for the stability and safety of superconducting coil during operation. To accurately predict the electro-magnetic and mechanical characteristics of superconducting coil in strong magnetic field, an electromechanical model on the basis of the H-formulation and arbitrary Lagrangian-Eulerian (ALE) method is proposed here with FE software. To verify the proposed model, the simulation outcomes of the coil during magnetization are compared with the experimental outcomes. The coupling effect of magnet at high field strengths is dependent on the position of the coil. To reduce the screening current effect, the overshoot method with plateau is found superior to the traditional overshoot method, and an increase in the stabilization time can decrease the maximum value of stress. Finally, the electromechanical behaviors of single winding coil and two-tapes co-winding coil are compared. Table and Figures | Reference | Related Articles | Metrics | Comments（0）

Pressurization, intercalation, doping, and elements: An empirical study of superconductivity near perturbation onsets Shermane M. Benjamin Superconductivity    2024, 10 (0): 100098-.   DOI: 10.1016/j.supcon.2024.100098 Abstract （161）   HTML （133）    PDF（pc） （1976KB）（2257）       Knowledge map    Save Superconductivity is a phenomenon arising from cooperative electron behavior. However, correlations among (1) the minimum tuning parameter required for emergence, (2) the superconducting transition temperature resulting from minimal tuning, and (3) the host's physical/chemical properties still elude the scientific community. Recent empirical investigations, such as those revealing ideal gas-like correlations at the onset of superconductivity in intercalated superconductors, motivate this study. Our investigation reports similar findings in systems (>170 compounds) exhibiting superconductivity through other perturbative means, such as single-element doping. In general, statistical measures, including distance correlation analyses (≠ linear regression fit) of thermodynamic variables, indicate the presence of empirical relationships near the superconducting onset of systematically tuned compounds. These relations involve unit cell volume (V), the number of valence electrons (N), and the superconducting transition temperature (Tc). Note: The author's primary aim is not to validate or challenge BCS theory; it is instead to focus on leveraging methodology led by available data to enhance the exploration and development of innovative and cost-effective superconductors.

Trends in global major disease burden and health conditions—interpretation of the Global Burden of Disease Study 1990-2021 FAN Bonan, LI Yan Journal of Diagnostics Concepts & Practice    2024, 23 (05): 474-483.   DOI: 10.16150/j.1671-2870.2024.05.003 Abstract （749）   HTML （43）    PDF（pc） （3009KB）（1727）       Knowledge map    Save The Global Burden of Disease Study 2021 (GBD 2021) analyzed 371 diseases and injuries using 100,983 data sources, estimating years lived with disability, years of life lost, disability-adjusted life years, and healthy life expectancy. From 1990 to 2019, the annual rate of change in global all-cause mortality ranged from -0.9% to 2.4%, while deaths increased by 10.8% and 7.5% in 2020 and 2021 respectively due to COVID-19. In 2021, COVID-19 was the second lea-ding cause of death globally, with a mortality rate of 94.0 per 100 000. The mortality rates of other major causes, such as ischemic heart disease and stroke were 108.7 and 87.4 per 100 000, respectively. Global life expectancy rose from 65.5 years in 1990 to 73.3 years in 2019 but dropped to 71.7 years in 2021 due to COVID-19, which reduced life expectancy by 2.2 years, significantly impacting the trend of health improvement. In China, GBD 2021 data shows a significant increase in life expectancy from 1990 to 2021: from 69.9 to 80.7 years for women and from 65.7 to 74.9 years for men. However, non-communicable diseases such as cardiovascular diseases, cancers, and chronic respiratory diseases remain major health threats. In 2021, these diseases had the highest burden among the top ten causes in China, with rising incidence and morta-lity rates. Major health risk factors in China include tobacco, hypertension, and dietary risks. This paper, through the systematic analysis of GBD 2021 data, reveals current trends in disease burden globally and in China, and proposes public health strategy recommendations. China should enhance chronic disease management, improve public health emergency responses, address health inequalities, and promote basic research and international cooperation to improve overall health levels.

Corpus Assisted Approach to Discourse Analysis of Textbooks: A Case Study of College English Textbooks PAN Chengjun Contemporary Foreign Languages Studies    2024, 24 (4): 83-94.   DOI: 10.3969/j.issn.1674-8921.2024.04.008 Abstract （225）   HTML （9）    PDF（pc） （1525KB）（1672）       Knowledge map    Save This paper adopts the methods of combining critical discourse analysis with corpus linguistics, quantitative and qualitative comparison between local textbooks and global textbooks, discusses cultural representation in College English textbooks, and analyzes its impact on cultural representation from the perspective of register type and language characteristics, so as to clarify the differences in structural features and social attributes of language textbooks under different social and cultural backgrounds and guiding ideology. The results show that the local materials reflect the relational thinking of Chinese philosophical thought in terms of subject matter and help to construct foreign language learners’ identities by bringing them closer to learners through dialogical genres and micro-level linguistic features, thereby recontextualizing the language materials in the local materials. On the other hand, local textbooks can be further expanded in terms of subject matter, knowledge, and international perspectives, and they also need to work on how to build China’s image and tell China’s story at the level of national consciousness. This study has implications for the writing, evaluation, and adaptation of foreign language textbooks in the new era. Table and Figures | Reference | Related Articles | Metrics | Comments（0）

Online Steady-State Scheduling of New Power Systems Based on Hierarchical Reinforcement Learning ZHAO Yingying, QIU Yue, ZHU Tianchen, LI Fan, SU Yun, TAI Zhenying, SUN Qingyun, FAN Hang Journal of Shanghai Jiao Tong University    2025, 59 (3): 400-412.   DOI: 10.16183/j.cnki.jsjtu.2023.344 Abstract （1425）   HTML （2）    PDF（pc） （4192KB）（1609）       Knowledge map    Save With the construction of new power systems, the stochasticity of high-proportion renewable energy significantly increases the uncertainty in the operation of the power grid, posing severe challenges to its safe, stable, and economically efficient operation. Data-driven artificial intelligence methods, such as deep reinforcement learning, are becoming increasingly important for regulating and assisting decision-making in the power grid in the new power system. However, current online scheduling algorithms based on deep reinforcement learning still face challenges in modeling the high-dimensional decision space and optimizing scheduling strategies, resulting in low model search efficiency and slow convergence. Therefore, a novel online steady-state scheduling method is proposed for the new power system based on hierarchical reinforcement learning, which reduces the decision space by adaptively selecting key nodes for adjustment. In addition, a state context-aware module based on gated recurrent units is introduced to model the high-dimensional environmental state, and a model with the optimization objectives of comprehensive operating costs, energy consumption, and over-limit conditions is constructed considering various operational constraints. The effectiveness of the proposed algorithm is thoroughly validated through experiments on three standard test cases, including IEEE-118, L2RPN-WCCI-2022, and SG-126.

Modeling of Multi-Modal Knowledge Graph for Assembly Process of Wind Turbines with Multi-Source Heterogeneous Data HU Zhiqiang, LIU Mingfei, LI Qi, LI Xinyu, BAO Jinsong Journal of Shanghai Jiao Tong University    2024, 58 (8): 1249-1263.   DOI: 10.16183/j.cnki.jsjtu.2023.062 Abstract （540）   HTML （19）    PDF（pc） （11842KB）（1533）       Knowledge map    Save The assembly process information of wind turbines is usually scattered in process documents consisting of multi-modal information, such as 3D models, natural texts, and images. Therefore, the cost of maintaining data and extracting process knowledge is high while the efficiency is low. To solve this problem, a multi-modal knowledge graph-based modeling method for the assembly process knowledge of wind turbines is proposed with multi-source heterogeneous data. First, the concepts in multi-modal process knowledge graph of wind turbine (MPKG-WT) are defined by analyzing the process characteristics of wind turbines to complete the construction of ontology. Then, based on the characteristics of multi-source heterogeneous data and multi-modal information, data analysis, knowledge extraction, and semantic similarity calculation are leveraged to realize the automatic instantiation of the graph. Finally, taking the process data of a wind turbine enterprise as an example, MPKG-WT is constructed and verified by implementing an auxiliary system for process design. The results show that MPKG-WT is more informative than the single-modal graph, and the data in different modals can complement each other, which leads to significant improvements in the efficiency of process design.

Therefore, it is necessary to establish a wind farm short-circuit fault time equivalence model. A wind farm short-circuit fault dynamic equivalence method considering the effect of wake effect is proposed. First, the wake effect factor is defined to reflect the degree of the unit affected by the wake effect. Then, the wake effect factor is used as the grouping basis to reduce the variability of operating state of the units within the group under the influence of the wake effect. A positive- negative- zero-sequence network equivalence method is analyzed to improve the effectiveness of the equivalence model in asymmetric short-circuit faults. An equivalence method suitable for zero-sequence network is proposed and a platform is built for verification. The simulation results show that the dynamic short-circuit fault equivalence model proposed can accurately reflect the active and reactive short-circuit output characteristics of wind farms under the influence of the wake effect.

Depth Distribution Characteristics of Particle Velocity Field Intensity in Shallow Sea ZHANG Haigang, XIE Jinhuai, LIU Jiaqi, GONG Lijia, LI Zhi Journal of Shanghai Jiao Tong University    2024, 58 (7): 995-1005.   DOI: 10.16183/j.cnki.jsjtu.2023.073 Abstract （1573）   HTML （9）    PDF（pc） （6512KB）（1312）       Knowledge map    Save The depth distribution characteristics of particle velocity field intensity have had a significant impact on underwater acoustic detection and estimation. In this paper, based on the approximate conditions of the incoherent normal modes sum transformation to angular integration, the angular integration form of incoherent normal modes of particle velocity was derived, which avoided the complex calculations of eigenvalues and eigenfunctions while revealing the physical mechanism behind the significant variations in particle velocity intensity with source depth and symmetrical depth. The numerical results demonstrate that the analytical expression of the angular integration of incoherent particle velocity can facilitate fast computation and effectively characterize the depth distribution characteristics of particle velocity intensity. Additionally, due to the superposition effect of the amplitude function of normal modes, there are notable differences in the depth distribution of vertical and horizontal particle velocity. Subsequently, focusing on the intensity difference of particle velocity, the study analyzed the effects of parameters such as horizontal distance, source frequency, sound speed profile, and water depth on the depth distribution characteristics of particle velocity field intensity. The findings provide a theoretical basis for passive target depth estimation based on vector fields. Table and Figures | Reference | Related Articles | Metrics | Comments（0）

Advances of facial skin typing methods  CHEN Zixuan, ZHANG Zheng, ZHANG Yixin Journal of Tissue Engineering and Reconstructive Surgery    2024, 20 (3): 378-.   Abstract （151）      PDF（pc） （954KB）（1290）       Knowledge map    Save Skin typing is a common method for describing skin characteristics. Traditional skin typing methods （such as the Fitzpatrick Skin Phototype and Baumann Skin Typing） have their own advantages and disadvantages. However， the above skin typing methods rely on subjective judgement， lacking quantitative analysis of skin objective parameters. In recent years， the measurement technology of objective parameters such as sebum secretion and transepidermal water loss has made great progress， making it possible to describe skin types with objective parameters. Additionally， image recognition technology based on facial photos can extract facial skin features and provide a basis for skin typing. This article reviewed subjective skin typing methods， skin objective parameter detection， and skin analysis technology based on image recognition， and discussed the development process of skin typing from qualitative-quantitative-visualization， in order to provide a theoretical basis for objective and precise skin typing in the future.

Low Carbon Economy Optimization of Integrated Energy System Considering Electric Vehicle Charging Mode and Multi-Energy Coupling ZHANG Cheng, KUANG Yu, CHEN Wenxing, ZHENG Yang Journal of Shanghai Jiao Tong University    2024, 58 (5): 669-681.   DOI: 10.16183/j.cnki.jsjtu.2022.364 Abstract （1437）   HTML （14）    PDF（pc） （4514KB）（1195）       Knowledge map    Save In order to enable a multi-energy coupling integrated energy system (IES) to meet the needs of load diversity in low-carbon economic operation, a bi-level optimal configuration method for low-carbon economic operation of multi-energy coupling IES in different charging modes of electric vehicles (EVs) is proposed. First, an IES including cold-thermal-electric-gas coupling is established. Then, in the day-to-day operation stage, factors such as hierarchical carbon trading mechanism and different charging modes of EVs are considered to achieve the lowest daily scheduling cost. In the configuration planning stage, based on the daily operation cost, the equipment capacity is configured with the lowest equipment investment cost and annual operation cost. Finally, Cplex is used to solve the above two-stage objective functions and obtain the optimal configuration scheme and scheduling results through mutual iteration. The results show that the charging method considering the remaining charge of EVs and carbon trading mechanism can significantly reduce carbon emissions and operating costs of the system. The proposed configuration approach can well realize low-carbon economic operation of the multi-energy coupling IES. Table and Figures | Reference | Related Articles | Metrics | Comments（0）

Numerical Study of Combustion Characteristics of Methane/Hydrogen Hybrid Fuel of Lean Premixed Swirl WANG Xinci, LIU Aiguo, WU Xiaoqu, ZHANG Yunjie Journal of Shanghai Jiao Tong University    2024, 58 (8): 1179-1187.   DOI: 10.16183/j.cnki.jsjtu.2022.502 Abstract （244）   HTML （14）    PDF（pc） （22873KB）（1177）       Knowledge map    Save The numerical simulation method is used to study the influence of the mixing ratio of methane/hydrogen mixture on the combustion characteristics and pollutant emission characteristics of the combustor. The results show that due to the action of combustion chemical reaction, there exists a certain difference in the structure of cold and hot flow fields. The flow velocity of the hot flow field increases, and the recirculation zone becomes larger. The hydrogen content has a significant impact on the structure and temperature distribution characteristics of the hot flow field, and a central recirculation zone is formed when the hydrogen content is less than 20%, which can maintain stable combustion. When the hydrogen content is greater than 40%, the central recirculation zone disappears, the external recirculation zone is extended, and the spontaneous combustion and flashback occur to varying degrees. As the inlet air temperature increases, the spontaneous ignition phenomenon becomes more obvious, and the inlet air temperature decreases, the flashback phenomenon becomes more obvious. NOx emissions increase with the increase of hydrogen content, CO emissions decrease with the increase of hydrogen content, and CO is concentrated in the combustion zone of the main combustion stage.

Advances in study on diagnosis and treatment of immune-mediated necrotizing myopathy LIU Hongjiang, XIE Qibing Journal of Diagnostics Concepts & Practice    2024, 23 (03): 270-277.   DOI: 10.16150/j.1671-2870.2024.03.004 Abstract （1091）   HTML （19）    PDF（pc） （935KB）（1104）       Knowledge map    Save Immune-mediated necrotizing myopathy (IMNM) is a significant, subtype of idiopathic inflammatory myopathy（IIM）, characterized by symmetrical proximal limb muscle weakness and markedly elevated serum creatine kinase levels. Some patients may also exhibit extra-skeletal muscle manifestations, including rashes, interstitial lung disease, and myocardial involvement. Since its international nomenclature in 2003, IMNM has gained increasing recognition among researchers and clinicians, leading to numerous scientific investigations and clinical applications. The incidence and prevalence of IMNM can vary across different geographic regions and ethnic groups. A small sample survey conducted in the United States reported an incidence of 0.83 per 100,000 and a prevalence of 1.85 per 100,000. In northern Spain, among patients positive for anti-HMGCR antibodies, the incidence was found to be 0.6 per 100,000, with a prevalence of 3 per 100,000. However, there is a notable paucity of relevant data regarding IMNM in China. Identified risk factors for IMNM include susceptibility alleles (e.g., HLA-DRB1*11), the use of statins or immune checkpoint inhibitors, and viral infections. Diagnosing IMNM requires a comprehensive evaluation that includes assessing muscle involvement symptoms, identifying myositis-specific autoantibodies, measuring creatine kinase levels, analyzing muscle biopsy pathology, and conducting related examinations. Currently, there is a lack of prospective randomized controlled studies on the treatment of IMNM. In clinical practice, glucocorticoids and traditional immunosuppressants are primarily employed on an empirical basis. For refractory cases, treatment regimens may involve rituximab and intravenous human immunoglobulin. Therapeutic strategies targeting B cells and the mechanisms underlying pathogenic autoantibody production may offer promising avenues for future treatment. This article systematically reviews the clinical characteristics, diagnostic criteria, relevant auxiliary examinations, and treatment strategies for IMNM, aiming to provide a comprehensive reference for clinicians in understanding, diagnosing, and managing this condition.

A Transformer-Based Diffusion Model for All-in-One Weather-Degraded Image Restoration QIN Jing, WEN Yuanbo, GAO Tao, LIU Yao Journal of Shanghai Jiao Tong University    2024, 58 (10): 1606-1617.   DOI: 10.16183/j.cnki.jsjtu.2023.043 Abstract （795）   HTML （12）    PDF（pc） （62692KB）（918）       Knowledge map    Save Image restoration under adverse weather conditions is of great significance for the subsequent advanced computer vision tasks. However, most existing image restoration algorithms only remove single weather degradation, and few studies has been conducted on all-in-one weather-degraded image restoration. The denoising diffusion probability model is combined with Vision Transformer to propose a Transformer-based diffusion model for all-in-one weather-degraded image restoration. First, the weather-degraded image is utilized as the condition to guide the reverse sampling of diffusion model and generate corresponding clean background image. Then, the subspace transposed Transformer for noise estimation (NE-STT) is proposed, which utilizes the degraded image and the noisy state to estimate noise distribution, including the subspace transposed self-attention (STSA) mechanism and a dual grouped gated feed-forward network (DGGFFN). The STSA adopts subspace transformation coefficient to effectively capture global long-range dependencies while significantly reducing computational burden. The DGGFFN employs the dual grouped gated mechanism to enhance the nonlinear characterization ability of feed-forward network. The experimental results show that in comparison with the recently developed algorithms, such as All-in-One and TransWeather, the method proposed obtains a performance gain of 3.68 and 3.08 dB in average peak signal-to-noise ratio while 2.93% and 3.13% in average structural similarity on 5 weather-degraded datasets.

The results show that the minimum geometric throat of the combustor affects the position of the thermal throat by changing the degree of obstruction in the combustor. With the increasing distance between the front edge of the cavity and the fuel injector port, the resulting low-speed zone presents a stronger blocking effect on the air flow, thus increasing the retention time of the particulate phase fuel and improving the combustion efficiency. The combustion efficiency of particulate phase fuel is the key factor that dominates the overall combustion efficiency, and affects the improvement of the combustor performance and the modification of combustion mode.
